Description

광반도체 조명기구 { LED Lighting Fixture }Optical Semiconductor Lighting Fixtures {LED Lighting Fixture}

본 발명은 건물의 천장이나 벽에 설치되어 실내를 원하는 조도로 유지시켜주는 조명기구로서, LED바를 광원으로 사용하여 기존의 형광등보다 수명이 길고 전력효율이 높으며, 구성 부품이 단순하여 설치 및 유지보수가 매우 간편한 새로운 방식의 LED 조명기구에 관한 것이다.
The present invention is a lighting fixture that is installed on the ceiling or wall of the building to maintain the interior of the desired illuminance, using a LED bar as a light source, longer life and higher power efficiency than conventional fluorescent lamps, simple components and installation and maintenance It is about a new way LED lighting fixture which is very easy.

형광등은 건물의 실내조명에 가장 많이 사용되는 광원으로서, 이러한 형광등은 형광램프와 안정기 등으로 구성되어 있다. 일반적으로 사용되는 조명기구는 대부분 형광등을 사용하고 있으며, 이러한 종래의 형광등은 60Hz의 교류전기를 사용하여 구동되므로, 형광램프의 빛이 1초에 60회 깜박거림으로 인하여 장시간 사용시 사용자가 눈의 피로를 쉽게 느끼게 되며, LED에 비하여 전력손실이 많고 사용 수명이 짧다는 단점이 있다.Fluorescent lamps are the most commonly used light sources for indoor lighting in buildings. These fluorescent lamps are composed of fluorescent lamps and ballasts. Most commonly used luminaires use fluorescent lamps, and these conventional fluorescent lamps are driven by using 60-Hz alternating current electricity. Therefore, the fluorescent lamp light flickers 60 times per second. It is easy to feel, and has a disadvantage in that there is more power loss and shorter service life than LEDs.

LED(Light-Emitting Diode)는 형광등에 비하여 소형이면서도 수명이 길뿐만 아니라 전기에너지가 빛에너지로 직접 변환되기 때문에 전력이 적게 소모되어 에너지 효율이 우수하다는 특징이 있다. 따라서, 이러한 LED를 광원으로 하는 다양한 종류의 조명기구가 개발되고 있는 실정이며, 근래에는 종래의 형광등을 대체할 수 있는 형광등 형태의 조명기구도 제시되고 있다.LED (Light-Emitting Diode) is smaller and longer lifespan than fluorescent lamp, and it is characterized by excellent energy efficiency because it consumes less power because electrical energy is directly converted into light energy. Therefore, various kinds of lighting fixtures using LEDs as a light source have been developed, and recently, lighting fixtures in the form of fluorescent lamps that can replace conventional fluorescent lamps have also been proposed.

그러나, 이러한 LED는 자체에서 많은 열이 발생하며, 고온에서는 광학적인 빛의 효율이 저하되고 수명이 현저히 줄어드는 단점이 있으므로 , 일정한 광학특성을 지속하고 수명단축을 막기 위해서는 LED에서 발생한 열을 신속히 방열시킬 필요가 있다. 또한, LED는 소형의 램프에서 고휘도의 빛을 방출하므로 직접 쳐다볼 경우 눈부심으로 인하여 일시적인 시력상실이 초래될 수 있기 때문에, LED를 조명기구로 사용하기 위해서는 넓은 면적으로 적절하게 빛을 확산시켜주는 장치가 필요하다.
However, these LEDs generate a lot of heat in themselves, and at a high temperature, the optical light efficiency is deteriorated and the lifespan is significantly reduced. There is a need. In addition, since LED emits high-brightness light from a small lamp, it may cause temporary blindness due to glare when looking directly. need.

본 발명은 위와 같은 종래의 형광등이 지닌 단점을 해소하기 위해서, LED바를 광원으로 사용하여 깜박임이 없는 양질의 빛을 얻고, 전력손실이 적으면서도 오래도록 사용할 수 있는 새로운 방식의 LED 조명기구를 제공하고자 한다.
The present invention to solve the disadvantages of the conventional fluorescent lamps as described above, by using a LED bar as a light source to obtain a high quality light without flicker, and to provide a new method of LED lighting fixture that can be used for a long time with low power loss. .

상기 목적을 달성하기 위하여, 본 발명은 LED바를 광원으로 사용하는데 있어서, LED가 최상의 온도 조건으로 동작할 수 있도록 방열 면적이 넓은 몸체에 LED바를 부착하고, LED바의 상부와 하부에 반사판을 배치하여 LED에서 방출된 빛이 반사판에 반사되면서 넓게 확산 되어 실내에 전달되는 것을 특징으로 한다.
In order to achieve the above object, the present invention uses the LED bar as a light source, by attaching the LED bar to the body of a large heat dissipation area so that the LED can operate at the best temperature conditions, by placing a reflecting plate on the top and bottom of the LED bar The light emitted from the LED is reflected by the reflector and is widely spread and transmitted to the room.

기존의 형광등 조명기구는 등기구 몸체, 반사판, 안정기, 반투명커버, 램프, 램프소켓 등의 여러가지 부품의 결합으로 이루어졌으나, 본 발명에 의한 제품은 등기구 몸체와 반투명커버 같은 부품이 필요치 않으며, 하나의 전력공급장치로 여러 개의 등기구를 동시에 구동시킬 수 있으므로, LED바와 프레임만으로 이루어진 매우 단순한 구성이기 때문에 저렴한 단가로 양질의 빛을 얻을 수 있는 LED 조명기구의 제작이 가능하다.Conventional fluorescent lighting fixtures are made of a combination of various parts such as a luminaire body, a reflector, a ballast, a translucent cover, a lamp, a lampholder, but the product according to the present invention does not require components such as a luminaire body and a translucent cover, one power Since several luminaires can be driven at the same time by the supply device, it is possible to manufacture LED luminaires that can obtain high quality light at a low cost because it is a very simple configuration consisting only of LED bars and frames.

또한, 본 발명에 의한 LED 조명기구는 형광등에 비하여 전력이 적게 소모되므로 에너지 효율이 매우 우수하고, LED의 사용 수명이 길어서 램프를 자주 갈아 끼우는 불편함이 없으며, 양질의 조도를 제공할 뿐만 아니라, 사용되는 부품이 매우 간단하여 조명기구의 크기도 작고 무게는 가벼워서 건물에 시공하거나 유지 보수가 매우 용이 하다는 장점이 있다.In addition, the LED luminaire according to the present invention is very energy-efficient because it consumes less power than fluorescent lamps, the use life of the LED is long, there is no inconvenience to replace the lamp often, not only to provide high quality illumination, Since the parts used are very simple, the size of the luminaire is small and the weight is light, which makes it easy to install or maintain in a building.

또한, LED의 최대 단점인 발열 문제를 방열판 역할을 수행하는 면적이 넓은 프레임으로 인하여 신속하게 방열이 이루어져, LED가 안정적인 온도에서 구동되는 최상의 환경을 조성하였으며, LED의 또다른 단점인 높은 휘도는 빛이 상부프레임과 하부프레임에서 서로 반사되면서 넓게 확산 되도록 구성하여 LED의 강렬한 빛이 눈부심이 거의 없는 부드러운 빛으로 변환하는 장점이 있다.
In addition, the heat dissipation is rapidly performed due to the large area of the heat sink as the heat dissipation problem, which is the biggest disadvantage of the LED, thus creating the best environment for driving the LED at a stable temperature. The upper frame and the lower frame are reflected from each other and configured to diffuse widely, which has the advantage of converting the intense light of the LED into soft light with almost no glare.

본 발명을 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.The present invention will now be described in detail with reference to the accompanying drawings.

도 1의 단면도에 도시된 바와 같이, 본 발명의 LED 조명기구는 우선 본체 프레임이 상부프레임(11)과 하부프레임(12)으로 나뉘어 있으며, 상부와 하부프레임은 2개의 프레임 고정나사(13)를 사용하여 조립되어 결합 된다.As shown in the cross-sectional view of Figure 1, in the LED lighting device of the present invention, the main frame is first divided into the upper frame 11 and the lower frame 12, the upper and lower frames are two frame fixing screws (13) It is assembled and combined using.

여기서, 상부프레임의(11) 내부 아래쪽은 곡선으로 이루어져서, LED바에서 발산된 빛을 반사하여 실내로 고루 분산시키는 역할을 하게 되며, 곡선의 형태는 빛이 넓게 확산 되거나 좁게 확산 되는 등의 배광특성에 따라 다양한 모양을 갖추게 된다. 또한, 상부프레임(11)은 하부프레임(12)에 비해 넓은 면적을 갖고 있으므로, 하부프레임(12)에서 전도된 열을 전달받아 신속하게 방열하는 역할도 동시에 수행하게 된다.Here, the inner bottom of the upper frame 11 is made of a curved line, which reflects the light emitted from the LED bar and distributes it evenly to the room. The shape of the curved line has a light distribution characteristic such that light is widely spread or narrowly spread. According to the various shapes. In addition, since the upper frame 11 has a larger area than the lower frame 12, the upper frame 11 also receives heat transferred from the lower frame 12 to perform a heat dissipation at the same time.

또한, 하부프레임(12)의 안쪽에는 LED바(10)가 부착되는 벽이 구성되어 있으며, LED바(10)가 부착되는 양쪽의 벽 사이에는 "ㄷ"자의 공간이 형성되어 있어서, LED바(10)와 전원공급장치를 연결하는 전선의 통로로 이용된다. 아울러, 하부프레임(12)은 금속재질로 제작되어 LED에서 발생한 열을 신속하게 방열시키고, LED에서 방출된 빛을 손실없이 상부프레임(11) 쪽으로 반사시키는 역할을 수행하게 된다.In addition, a wall to which the LED bar 10 is attached is configured on the inside of the lower frame 12, and a space between the two walls to which the LED bar 10 is attached is formed with a space of “c”, so that the LED bar ( 10) is used as a passage for electric wires to connect the power supply. In addition, the lower frame 12 is made of a metal material to quickly dissipate heat generated from the LED, and serves to reflect the light emitted from the LED toward the upper frame 11 without loss.

상기의 상부프레임(11)에서 빛이 반사되는 내부 아래쪽은 빛이 부드럽게 난반사 되도록 하기 위해서 표면에 요철을 주거나 난반사 재질로 코팅되어 있고, 하부프레임(12)에서 빛이 반사되는 내부 위쪽은 빛이 손실 없이 상부프레임(11)으로 반사될 수 있도록 거울과 같은 기능을 갖도록 표면처리가 되어 있다.The inner lower part where the light is reflected from the upper frame 11 is coated with irregularities or a diffuse reflection material in order to smoothly reflect the light, and the upper upper part where the light is reflected from the lower frame 12 loses light. Surface treatment is performed to have a mirror-like function so that it can be reflected to the upper frame 11 without.

LED의 전원공급장치(20)는 전원공급장치의 몸체(21)에 별도로 내장되어 조명기구의 상부프레임(11) 위에 고정고리(14)를 이용하여 부착된다. 형광등기구의 경우 등기구 하나당 별도의 전원공급장치가 반듯이 필요하지만, 본 발명에 의한 조명기구에서는 LED의 전력소모량이 적으므로, 하나의 전원공급장치로 보통은 20~30개의 등기구를 한꺼번에 연결할 수가 있다. 만일, 조명기구를 펜단트 타입(Pendent Type)으로 제작하는 경우에는, 도 4에 도시된 바와 같이 전원공급장치의 몸체(21)에 펜단트 파이프(22)를 연결하여 조명기구를 천장에 매달게 되며, 조명기구가 길이방향으로 여러 개가 연결되어 설치되지 않고 단독으로 설치되는 경우에는 엔드캡(15)을 양쪽 끝에 부착하여 조명기구의 끝단 쪽으로 LED의 빛이 직접 새어 나오는 것을 방지하게 된다.The power supply device 20 of the LED is separately embedded in the body 21 of the power supply device and attached to the upper frame 11 of the luminaire using the fixing ring 14. In the case of fluorescent lighting fixtures, a separate power supply is required for each lighting fixture. However, since the power consumption of the LED is small in the lighting fixture according to the present invention, one to one power supply can usually connect 20 to 30 lighting fixtures at once. If the lighting fixture is manufactured in a pendant type, the pendant pipe 22 is connected to the body 21 of the power supply as shown in FIG. 4 to hang the lighting fixture on the ceiling. When a plurality of lighting fixtures are installed alone without being connected in the longitudinal direction, the end cap 15 is attached to both ends to prevent the light of the LED from directly leaking toward the end of the lighting fixture.
